FIELD: materials for plate separators of chemical current supplies and storage batteries.
SUBSTANCE: proposed nonwoven material for alkali current supply separators is made of extremely thin polysulphone fiber having pore diameter of maximum 6 μm and surface density of 26 - 39 g/cm2. Method for producing such material includes electric formation of extremely thin polysulphone fibers and their compression followed by treatment with surface-active material.
EFFECT: enhanced moisture and alkali absorption capacity, reduced electrical resistance, and enhanced chemical stability.
